METHOD FOR PRODUCTION OF COPOLYMER OF ETHYLENE AND PENTENE-1, COPOLYMER OF ETHYLENE AND PENTENE-1 AND POLYMER COMPOSITION Russian patent published in 1997 - IPC

Abstract RU 2091401 C1

FIELD: production of film having high impact resistance, high ultimate strength and high transparency even after affection of heat. SUBSTANCE: novel copolymers of ethylene and pentene-1, method for their production and method for production of compositions comprising said copolymer together with stabilizing agent are proposed here. Composition of copolymer ethylene and pentene-1 has high stability by formation and is high resistant against thermal ageing and affection of atmosphere. EFFECT: improved efficiency of the method, improved quality of desired product. 7 cl, 2 dwg, 4 tbl
